Fat-shamers are reportedly handing out anti-gluttony cards to commuters on London public transportation, trying to convince strangers to change their allegedly unhealthy lifestyles.

The cards are credited to "Overweight Haters Ltd." Kara Florish says she was given the card while traveling on the London Underground and shared images of the card on social media.

"It's really not glandular, it's your gluttony," the card states, according to Florish’s posts. "Our organization hates and resents fat people. We object to the enormous amount of food resources you consume while half the world starves."

"We do not understand why you fail to grasp that by eating less you will be better off, slimmer, happy, and find a partner who is not a perverted chubby-lover, or even find a partner at all," the card continues.

"We also object that the (beautiful) pig is used as an insult. You are not a pig. You are a fat, ugly human."

British Transport Police confirmed that they are aware of the cards being distributed and urged anyone who has received one to contact authorities.

Florish is taking the situation in stride.

"I am not upset myself," Florish wrote online. "I am smaller than the national average and not exactly obese, but this is hateful and cowardly and could potentially upset people struggling with confidence and eating disorders."

Another traveler, Sean Thomas Knox, reported seeing a woman break down in tears after receiving one of the cards.

"Young man just got on train at Oxford Circus, gave printed card saying YOU'RE FAT to overweight girl. He jumped off. She read it, & cried," he wrote on Twitter. "Am 99.9% sure this wasn't staged. She didn't even realise I was watching at first. Her stunned, desolate reaction was very real. Then tears."
